Why does a show have to be "high definition" to be on Blu-ray?

[The Lion King]

I'm just assuming that the video on a DVD isn't the same size and quality as the uncompressed master video. Why can't they just put the uncompressed master video on a Blu-ray disc? Surely that would look ten times better than a DVD? No? [/noob]

I dont know anything but im just assuming that the file size for a complete master of a film would be monstrous. at least more recent films. but hey i dont really know what im saying.

[MGDTH]

Digital Cinema movies 4k are 250gb so 2k (Fullhd) would be 125-150gb with date rate 125MB/S, Blu-ray has theoretical bandwidth of 72Mb currently.

Something tells me that the first master in rasterization/scanning process is somewhere in neighborhood of one terabyte.

Still think that we would use the non-optmized master?



encoding using the ISO/IEC 15444-1 "JPEG2000" (.jp2) standard and use of the CIE XYZ color space at 12 bits per component encoded with a 2.6 gamma applied at projection, and audio using the "Broadcast Wave" (.wav) format at 24 bits and 48 kHz or 96 kHz sampling, controlled by an XML-format Composition Playlist, into an MXF-compliant file at a maximum data rate of 250 Mbit/s. Details about encryption, key management, and logging are all discussed in the specification as are the minimum specifications for the projectors employed including the color gamut, the contrast ratio and the brightness of the image.

What master? If it's video it's either HD or SD. If it's SD it won't look that much better on HD than the DVD. Better, but not worlds. At this stage it's logical to push HD content and not SD if you have to convince people to buy into the new format. It's difficult enough to make people see that HD is more than marginally better than SD on smaller screens.

They already put some SD content on Blu rays.

On The Dirty Dozen Blu ray they include the Tele Movie sequel.

One thing is it should be a lot less "compressed" hence less compression artifacts.

it wont look any better then a dvd by doing that the only thing that will do is put a tv show on a 50gb disc with scratch resistant coating on the disc . so in a way it would be like a super dvd-blu-ray disc with no quality except for what we are used to from watching tv on standard definition tvs

"Why does a TV show have to be high definition to be on Blu-ray?"

To answer your question... BECAUSE NOBODY WOULD SPEND $90+ FOR A DVD QUALITY SEASON OF A TV SHOW! I sure as shit would NOT buy a Blu-ray disc if it contained anything OTHER than a high definition copy of the feature presentation.

NOTE TO EVERYONE: I do not mean "Why does a show have to be in high defintion to go on Blu-ray" as in they'd just be putting DVD quality and sized video on audio with all DVD features. What I meant and tried to say was why can't shows that weren't shot in High definition (Scrubs, The Simpsons, etc.) be released on Blu-ray except compressed to 50 gb to fit on a Blu-ray. It would mean about 6x better quality and would look similar to some BDs already released on Blu-ray.

Sorry, I should've explained that better before.

I guess there are newer shows they can guaranteed to get more money? I mean they know releasing Lost 4 is worth but to go back and release Lost 1 again would be risky. I've talked to many people saying they're not gonna buy Heroes Season 1 on BD but will buy Season 2 on BD just because they already have the DVD version. Unlike movies which you can repeat it over and over, most of these shows ,for most people, they can only be watch one time in a long long while.

But for me I'll buy both season 1 and 2 on BD and maybe 2nd one on DVD just because I' want them to be match. LOL

No, that is not viable for a multitude of reasons.

Uncompressed video required bandwidth far above what Blu-ray is intended for, even SD quality uncompressed video.

Pretty much everything these days is shot in HD, and animated series or movies are usually renederd in HD too and downconverted for SD broadcast.

Just because it is 4:3 doesn't mean it's not HD. Anything shot on film can be mastered in HD, so stuff like Friends or Seinfeld which is not in 16:9 can be remastered and released on Blu-ray in 1440x1080.

Because it's not going to look 6x better. The return is marginal at best

I have the Yukikaze Blu-ray, which is a high bandwidth (35mbps average video) compression and professional upconversion of what is essentially computer animation. Pretty much the purest source possible

The gains are minimal at best when A/B'd with upconversion. All you're losing is compression artifacts, but gains in detail are minimal.

When people buy Blu-ray, they expect HD. The bang for the buck simply is not there for SD material

I think I'm the only one.

No it didnt.

[DocNovak]

I have to say that there are shows that I would buy on blu-ray even if they were not in HD because they were shot in SD Video. I don't know which older shows were shot on film and which on video, and those that were shot on film I would expect them to be remastered/rescanned in HD. But I would buy shows like Cheers, or Night Court on Blu, even if they were shot on video and could not be remastered/rescanned into HD just so I could have an entire season on one disc, and the whole series on a handful of discs. Just my 2¢.

Just watch them, it's painfully obvious which ones are video.

Cheers has been rescanned for HD, just don't expect it for a long while after they finish it on DVD

They will never release SD series on Blu-ray just to stuff them on less discs. Use the search function to find exhaustive explanations why

search what... "sd blu ray" ?

I understand the reasons why, and I understand that they won't be doing it anytime soon (I don't say never, because if Blu-Ray becomes the dominant format for the next 20+ years, who knows what they will do in that time, but highly, highly doubt it) I am just saying that I would be willing to buy them if they did (again only shows that were really good, but were shot on video and therefor could not be remastered/rescanned into HD).

Which raises my next question. What is the likelyhood of them spending time, energy and resources to do a frame by frame upscaling of SD video and then putting that on a blu-ray, instead of just having player upscale on the fly? I have to say, last night my wife was watching TBS HD and it was painfully obvious that the show she was watching was a poorly upscaled version of an SD broadcast (broadcast at 1080i) it was horrible and I avoid the HD channels that do that on cable.

PS - Thanks for the info on cheers.

Virtually none. A good quality DVD vs a careful upscale is marginal difference at best. I expect it to be all the rage in Japan though on older anime titles.

You must have forgotten how expensive "Band of Brothers" was on dvd. And that sold a lot of copies. HBO tends to charge a premium price for all their shows. It's why I don't buy any of their series. Though I might buy the bd version of Band of Brothers, because I am guessing it will be incredible.
